Lumbar Lordosis Morphology Correlates to Erector Spinae Muscularity in Asymptomatic Asian Adults

Abstract Background It is still blank on the relationship between lumbar lordosis morphology and paraspinal muscle in asymptomatic Asian adults. The study aims to investigate the relationships. Methods 87 asymptomatic adults aged between 18 and 45 years old were enrolled in the retrospective study. Lumbar lordosis morphology, consisting of total lumbar lordosis (LL), proximal lumbar lordosis (PLL), distal lumbar lordosis (DLL), lumbar lordosis apex (LLA) and inflexion point (IP), was evaluated, as well as pelvic incidence (PI) and muscularity of erector spinae (ES) and multifidus (MF). Pearson correlation was performed to analyze the relationship between each other parameter. Cases were stratified according to pelvic incidence (very low < 30°, low 30°-45°, moderate 45°-60°, and high > 60°), comparison between groups was performed by univariance analysis. Results PLL revealed a correlation with LLA (r = 0.603, p = 0.002) and inflexion point (r = 0.536, p = 0.004), but did not DLL with LL apex (r = 0.204, p = 0.058) or inflexion point (r = 0.210, p = 0.051). PI revealed a greater correlation with PLL (r=-0.673, p < 0.001) than with DLL (r=-0.237, p = 0.045). Linear stepwise regression analysis also exhibited the correlation between PI and PLL (R2 = 0.452, PLL = 16.2–0.61*PI, p < 0.001). ES muscularity correlated with LL apex (r=-0.279, p = 0.014) and inflexion point (r=-0.227, p = 0.047). Stratification by PI demonstrated PLL increased across groups (p < 0.001), but DLL was comparable between low and moderate PI group (p = 0.329). Conclusion Lumbar lordosis morphology correlates to erector spinae muscularity. Proximal lumbar lordosis has a bigger correlation with pelvic incidence than the distal lumbar lordosis. The results are helpful for restoring a rational lumbar lordosis shape in long fusion surgery.

AbstractThe retrospective study aimed to investigate the relationship between lumbar lordosis morphology, pelvic incidence and paraspinal muscle. It enrolled asymptomatic adult volunteers aged between 18 and 45 years old. Lumbar lordosis morphology, consisting of total lumbar lordosis (LL), proximal lumbar lordosis (PLL), distal lumbar lordosis (DLL), lumbar lordosis apex (LLA) and inflexion point, was evaluated, as well as pelvic incidence (PI) and muscularity of erector spinae (ES) and multifidus. Pearson correlation was performed to analyze the relationship between each other parameter. Cases were stratified according to pelvic incidence (very low < 30°, low 30°–45°, moderate 45°–60°, and high > 60°), comparison between groups was performed by univariance analysis. 87 asymptomatic adult volunteers (33 females and 54 males) were included in the study. PLL revealed a correlation with LLA (r = 0.603, p = 0.002) and inflexion point (r = 0.536, p = 0.004), but did not DLL with LL apex (r = 0.204, p = 0.058) or inflexion point (r = 0.210, p = 0.051). PI revealed a greater correlation with PLL (r = −0.673, p < 0.001) than with DLL (r = −0.237, p = 0.045). Linear stepwise regression analysis also exhibited the correlation between PI and PLL (R2 = 0.452, PLL = 16.2–0.61 * PI, p < 0.001). ES muscularity correlated with LL apex (r = −0.279, p = 0.014) and inflexion point (r = −0.227, p = 0.047). Stratification by PI demonstrated PLL increased across groups (p < 0.001), but DLL was comparable between low and moderate PI group (p = 0.329). Lumbar lordosis morphology appears to accommodate to pelvic incidence and erector spinae muscularity. Proximal lumbar lordosis has a bigger correlation with pelvic incidence than the distal lumbar lordosis. The results are helpful for restoring a rational lumbar lordosis shape in long fusion surgery.

Abstract Objective To measure the sagittal configurations of the sacrum using computed tomography (CT), and to investigate the correlation between the sagittal configuration of the sacrum and pelvic incidence. Methods The computed topographies of complete pelvic imaging between 2006 and 2018 was retrospectively studied. Measurements of pelvic and sacral morphological parameters were performed on the midsagittal plane of the 2D reconstruction images of computed tomography. Pelvic incidence (PI) (STA) were measured as previously described, and sacral table angle, sacral incidence (SI), sacral segmental vertebral angle (SSVA), sacral segmental kyphosis (SSK), central angle (SCA), arc length (SAL) as well as arc radius (SAR) were introduced to describe the segmental morphology of sacrum. Pearson Correlation Coefficient and Stepwise Regression Analysis were used to determine the relationship between PI and sacral morphological parameters. Results A total of 304 subjects were finally included in this study. The average age of the patients were 46.22 ± 15.92 years, and the average PI was 45.24±8.68°. Most of the sacral morphological parameters were not different as affected by gender or age. The morphological parameters of S1: S1I, SSVA1 and STA were finally confirmed to be closely correlated with PI, while no significant correlation between sacral curvature (SCA) and PI was identified, and morphological parameters of other sacral segments were not correlated to PI either. Conclusion The morphological parameters of S1 are more closely correlated with PI, and the sacral incidence of S1 might serve as a useful tool for the calculation of PI.

Abstract The objectives of this study were to examine the relationship between residual feed intake (RFI) and DM and nutrient digestibility, in vitro methane production, and volatile fatty acid (VFA) concentrations in growing beef cattle. Residual feed intake was measured in growing Santa Gertrudis steers (Study 1; n = 57; initial BW = 291.1 ± 33.8 kg) and Brangus heifers (Study 2; n = 468; initial BW = 271.4 ± 26.1 kg) fed a high-roughage-based diet (ME = 2.1 Mcal/kg DM) for 70 d in a Calan-gate feeding barn. Animals were ranked by RFI based on performance and feed intake measured from day 0 to 70 (Study 1) or day 56 (Study 2) of the trial, and 20 animals with the lowest and highest RFI were identified for subsequent collections of fecal and feed refusal samples for DM and nutrient digestibility analysis. In Study 2, rumen fluid and feces were collected for in vitro methane-producing activity (MPA) and VFA analysis in trials 2, 3, and 4. Residual feed intake classification did not affect BW or BW gain (P > 0.05), but low-RFI steers and heifers both consumed 19% less (P < 0.01) DMI compared with high-RFI animals. Steers with low RFI tended (P < 0.1) to have higher DM digestibility (DMD) compared with high-RFI steers (70.3 vs. 66.5 ± 1.6% DM). Heifers with low RFI had 4% higher DMD (76.3 vs. 73.3 ± 1.0% DM) and 4 to 5% higher (P < 0.01) CP, NDF, and ADF digestibility compared with heifers with high RFI. Low-RFI heifers emitted 14% less (P < 0.01) methane (% GE intake; GEI) calculated according to Blaxter and Clapperton (1965) as modified by Wilkerson et al. (1995), and tended (P = 0.09) to have a higher rumen acetate:propionate ratio than heifers with high RFI (GEI = 5.58 vs. 6.51 ± 0.08%; A:P ratio = 5.02 vs. 4.82 ± 0.14%). Stepwise regression analysis revealed that apparent nutrient digestibilities (DMD and NDF digestibility) for Study 1 and Study 2 accounted for an additional 8 and 6%, respectively, of the variation in intake unaccounted for by ADG and mid-test BW0.75. When DMD, NDF digestibility, and total ruminal VFA were added to the base model for Study 2, trials 2, 3, and 4, the R2 increased from 0.33 to 0.47, explaining an additional 15% of the variation in DMI unrelated to growth and body size. On the basis of the results of these studies, differences in observed phenotypic RFI in growing beef animals may be a result of inter-animal variation in apparent nutrient digestibility and ruminal VFA concentrations.

The aim of the current research is to investigate the relationship between the attitudes and motivation of EFL learners and their willingness to listen (WTL); possible effects of age and gender on EFL learners’ WTL, attitude and motivation. A quantitative study was designed in which 239 participants, intermediate level EFL learners at a public university, took a set of instruments, namely a reduced version of the AMTB, mini-AMTB, and WTL scale in Likert type. The participants were also asked to specify their gender and age during data collection procedure. Data was analysed using SPSS 24.0. Percentage and frequency analyses, independent samples t-test, Kruskal Wallis H test, Pearson correlation analysis and simple linear regression analysis were employed in data analysis phase. The results of the study showed that gender affects EFL learners’ attitudes and motivation while age has no effect on attitudes and motivation; also it was found that there is a positive and meaningful relationship between mini-AMTB and WTL scores of the participants. According to the findings of the current study the predictive power of mini-AMTB of WTL has been found statistically meaningful. The findings have revealed that there is a positive and meaningful relationship between mini-AMTB and WTL scores of the participants. Gender affects EFL learners’ attitudes and motivation as female participants’ mini-AMTB scores were found higher than those of male participants. Also a meaningful relationship between mini-AMTB and WTL has been found according to regression analysis. The paper concludes with implications for further research to investigate the WTL in various contexts with other personal variables.

Introduction The nursing literature is silent about the relationship between ethical leadership, nurses’ flourishing, and extra-role behavior. This study was carried out to contribute to the relevant field research. Objective The aim of the present study was to investigate the relationship between nurses’ perceptions of their nursing managers’ ethical leadership behavior, nurses’ flourishing, and their extra-role behavior. Methods This was a cross-sectional study involving 302 nurses from six hospitals in Damietta City, Egypt. Data were collected using the following three self-report scales: Ethical Leadership at Work questionnaire, Flourishing Scale, and extra-role behavior scale. The data were analyzed using descriptive statistical, Pearson correlation, regression analysis and the structure equation model. Results There was a significant positive relationship between nursing managers’ ethical leadership, nurses’ flourishing, and extra-role behavior. The regression analysis showed that the ethical leadership of nursing managers and nurses’ flourishing predict extra-role behavior. Conclusion Nurses with a high level of flourishing and who work with a manager exhibiting ethical leadership behavior are more likely to activate extra-role behavior. Hence, it is recommended that nursing managers embrace an ethical approach in their leadership practices and promote flourishing among nurses to encourage them to go the extra the mile in their jobs.

Background and Aims Fetuin-B has been reported to be involved in glucose and lipid metabolism and associated with the occurrence of diabetes. The main purpose of this study is to explore the changes of circulating fetuin-B in young women with pre-diabetes and to analyze the relationship between fetuin-B and the occurrence and development of IR. Methods A total of 304 women were enrolled in this study and subjected to both OGTT and EHC. A subgroup of 26 overweight/obese womenwas treated with Lira for 24 weeks. serum fetuin-B concentrations were measured by ELISA. Results In IGT and IR-NG groups, serum fetuin-B levels were higher than those in the NGT group. The serum fetuin-B levels in the IGT group were higher than those in the IR-NG group. serum fetuin-B was positively correlated with BMI, WHR, 2h-BG, FIns, HbA1c, and HOMA2-IR, but negatively correlated with the M-value in all study populations. Multiple stepwise regression analysis showed that the M-value was independently and inversely associated with serum fetuin-B. Logistic regression analysis showed that serum fetuin-B was independently associated with IGT and significantly increased the risk of IGT. During the OGTT, serum fetuin-B increased significantly in the NGT group, but there were no significant changes in other groups. During the EHC, serum fetuin-B increased in the IGT group, but there was no change in other groups. After Lira intervention, serum fetuin-B decreased significantly in IGT women. Conclusions serum fetuin-B levels are elevated in young women with IR or IGT and may be associated with IR.

Predictors Of Academic Achievement

The Actiotope Model of Giftedness (AMG) focuses on person-environment interactions instead of on the personality traits associated with actions. Motivation is a combination of intrinsic and extrinsic forces that are fundamental to the production of actions. Therefore, the resources provided by the environment or person are important for the creation of motivation. The aim of this study was to explore the relationship between resources and motivation components, and to determine which were predictors of academic achievement among Turkish students (440 students, 206 from the 4th grade and 234 from the 7th grade). The Questionnaire of Educational and Learning Capital (QELC) was used to assess the resources described in the AMG, and the Scale of Intrinsic Versus Extrinsic Motivational Orientation in the Classroom (IVEMOCS) was used to assess the motivation components. Findings showed significant correlations between all resources and two motivation components: intrinsic and dependence on the teacher. Using stepwise regression analysis, in 4th-graders, infrastructural capital and extrinsic motivation were found to predict academic achievement; and in 7th-graders, intrinsic motivation, economic capital, extrinsic motivation and didactic capital were found to predict academic achievement.

Aim: The purpose of this study was to assess the relationship between TrA muscle strength and lumbar lordosis in young adults. Methods: Total 394 subjects were recruited from the constituent institutions of Sumandeep Vidyapeeth with the age range 18-35years. All the subjects, Lumbar lordosis angle and their TrA strength were measured with the Flexicurve and Pressure Biofeedback Unit respectively. Lumbar lordosis angle was calculated using established formula. Average of 03 trials was considered for TrA strength. Results: Pearson correlation coefficient was -0.18 on correlating Lumbar lordosis angle with TrA strength, -0.09 for age with TrA strength and 0.11 for age with lumbar lordosis angle. Conclusion: This study concludes that there is negative relationship between lumbar lordosis and TrA i.e. as the lumbar lordosis angle increases, the strength of TrA muscle decreases.

Gingivitis is a reversible periodontal disease which does not destruct the supporting tissues. Studies have shown the relationship of smoking with gingivitis. There is no solid evidence of the same parameters in the Chennai area. Therefore, the focus of the current study is to find the interrelation between tobacco habit with the severity of gingivitis among 18-35-year-old adults attending a private college in Chennai.This retrospective study included all gingivitis index recorded patients in the age of 18-35-year-old adults. The data was obtained from the patient records in the college from June 2019 to March 2020 and examined by 2 examiners. Gingival index (1967) was used to measure the severity of the gingivitis. Descriptive statistics were expressed by means of frequency and percentage, chi-square was done to assess the association between age, tobacco use and gingivitis. Pearson correlation tests were done to identify the relationship of tobacco use and severity of gingivitis. In the present study with a sample size of 997, 62.19% males and 37.81% females were present. Prevalence of tobacco users in the study population was 25.77%. 52.66% had mild gingivitis, 40.92% had moderate and 6.42% had severe gingivitis. A significant positive correlation was observed between tobacco use and severity of gingivitis using Pearson correlation statistical test. With the results of the current study, it can be presumed that the severity of gingivitis was found to be more among tobacco users.
